Latest Patents

One of Xi Liu's latest patents is titled "Systems and methods for surgical data censorship." This invention relates to systems and methods for processing surgical data to facilitate further downstream operations. The disclosed embodiments may include machine learning systems trained to recognize whether video from surgical visualization tools, such as endoscopes, depicts a field of view inside or outside the patient body. The system may excise or whiteout frames of video appearing outside the patient to remove potentially compromising personal information, such as the identities of members of the surgical team and the patient's identity. Appropriate removal of such non-surgical data may facilitate downstream processing by complying with regulatory requirements and removing extraneous data that could hinder further processing.

Another notable patent by Xi Liu is "Systems and methods for predicting keypoint movement for multiple surgical instruments using spatial-temporal graph attention modeling." This method involves predicting the movement of keypoints of surgical instruments by receiving their locations and determining their trajectories. The process includes generating tool-level graphs that indicate spatial-temporal relationships between the keypoints and creating a scene-level graph based on these relationships. The output image generated from this method includes the predicted locations of the keypoints, enhancing the precision of surgical operations.
